DETAILED DESCRIPTION OF THE INVENTION

References will now be made in detail to the presently preferred embodiments and methods of the invention as illustrated in the accompanying drawings, in which like reference characters designate like or corresponding parts for all the drawings. It should be noted, however, that the invention in its broader aspects is not limited to the specific details, representative devices and methods, and illustrative example shown and described in this section in connection with the preferred embodiment and method. The invention according to its various aspects is particularly pointed out and distinctly claimed in the attached claims read in view of the specification, and appropriate equivalents.

Referring now to the drawings, FIGS. 1-7 illustrate a preferred embodiment of a combination drinking container and audio amplification device 10 embodying the present invention. The combination device 10 includes a drinking container 12 and a base assembly 14 which is sealingly and removably connected to a lower end of the container 12.

Drinking container 12 may have any size and shape desired but preferably has a bell-shaped sidewall structure 16 that flares outwardly and upwardly from an open cylindrical bottom 18 (FIG. 2) to an open cylindrical top 20. The sidewall structure 16 may or may not be thermally insulated depending on the need to preserve the temperature of the beverage to be held in the container 12. A handle 22 is secured to and runs substantially the length of an external length of the sidewall structure 16. The open bottom 18 of the container 12 is provided on its internal peripheral surface with a series of L-shaped retaining slots 24 (FIG. 2) to facilitate removable connection with the base assembly 14. Preferably, the container 12 and handle 22 are constructed from a rigid, durable washable material such as plastic commonly used to make reusable drinking vessels.

The base assembly 14 is comprised of a diaphragm 26, an O-ring 28, a circular speaker 30, a ring-like printed circuit board 32 with audio and electronic components, a push button switch 34, a generally cylindrical base 36, a battery 38, and a cover 40. An upper end of the base 36 is constructed with a skirt 42 having a set of protruding nibs 44 rotatably engageable with the walls of the slots 24. With this structure, the base 36 may be removably coupled to the lower end of the container 12 with the O-ring 28 interposed between the upper end of the base 36 and the open bottom 18 to provide a sealed, leak-proof connection as seen in FIGS. 3 and 4. It can also be seen that the O-ring 28 surrounds the diaphragm 26 which is positioned against and functions to close the open bottom 18 so that the beverage may be held sealed in the container 12. The diaphragm 26 may be preferably fabricated from plastic or Mylar which is sound conducting. The base 36 acts as a protective housing for the audio and electronic components and further with cover 40 is configured to provide stability for supporting the container 12 on a flat surface.

It is an important feature of the invention that the speaker 30 is oriented upwardly to emit sound waves directly towards the interior of the container 12 as will be appreciated below. The peripheral edge of speaker 30 is engageable with a first annular shoulder 46 (FIG. 3) formed inside the upper end of the base 36. The speaker 30 is shown spaced slightly below the diaphragm 26 but might be located more closely adjacent thereto. The diaphragm 26 covering the speaker 30 protects the speaker 30 from any beverage in the container contacting the speaker and other electronic components in the base 36. In the preferred embodiment, the speaker 30 extends across substantially the entire open bottom 18 of the container, but it should be understood that the speaker 30 could cover only a portion of the open bottom 18 if desired. In addition, a speaker 30 with a protective sealing covering (not shown) might be used in lieu of the diaphragm 26.

The ring-like printed circuit board 32 has a center recess 48 through which the lower portion of the speaker 30 protrudes. The upper end of the circuit board 32 is positioned against a second annular shoulder 48 formed inside the base 36. A peripheral edge of the circuit board 32 is notched to receive ribs 50 formed along the inside of the base 36. The printed circuit board 32 includes a capacitor 52, an amplifier circuit 54, a microphone 56, and switch sorting pads 58 which are selectively adjustable with manually actuable push button switch 34, all of which define a sound generating device.

The cover 40 is formed with respective upstanding walls 60, 62, 64 for retaining the battery 38 and microphone 56. The cover 40 further includes an inwardly curved extension 66 having an opening 68 for receiving the switch 34. The extension 66 fits into a cut-out 69 formed on base 36. Opposite sides of the cover 40 are provided with resilient catches 70 designed to snap into holes 72 formed on the lower end of the base 36 so that the cover 40 will be retained thereon. The cover 40 is constructed with support prongs 74 which hold the printed circuit board 32 in position when the cover 40 is coupled to the base 36. Also with the cover 40 in place, the top of the battery 38 supports the lower end of the speaker 30. Access to the microphone 56 inside the base 36 is provided by apertures 76 formed in the cover 40. Wiring 78 provides electrical communication among the speaker 30, the circuit board 32 and the battery 38.

In use, beverages may be poured into and consumed from the container 12 in normal fashion. With the container 12 emptied, a user is able to utilize the product as an electronically amplified megaphone by holding the container 12 as shown in FIG. 7, and by pushing the switch 34 with one's thumb and speaking, singing or otherwise conveying sound into the apertures 76 on the base 36 so that the particular sound will be reproduced as electronically amplified sound waves emitted from the speaker 30. The sound waves because of the particular upward orientation and positioning of the speaker 30, are projected through diaphragm 26 and into the container interior and are conducted along inside surfaces of the sidewall structure 16 for delivery through the open top 20 of the container 12. The sound waves are thus further amplified and the outwardly flaring sidewall structure provides for greater sound wave distribution.

Periodically, the base 36 may be uncoupled from the container 12 so that the latter may be washed or replaced if desired. The base 36 may be accessed to change the battery 38 as necessary by disconnecting resilient catches 70 and removing cover 40.

While the preferred embodiment discussed above discloses a sound generating device as including a microphone 56, the invention contemplates other types of sound generating devices to produce sounds from the speaker 30. Other examples of sound generating devices include a pre-recorded sound chip, a radio receiver, and an audio device such as an MP3 player connected externally to the circuit board 32 through a jack formed in the base 36. In addition, rather than using a manually-actuated switch 34, it may be possible to place a wireless receiver in the base 36 which will activate sound upon receiving a signal from a remote control.

While not shown, other versions of the invention are contemplated which may allow the drinking container to be partially filled with a beverage and still operate as an electronic amplification device.
